Zinc Stearate Nrog Cas 557-05-1
Zinc stearate yog hmoov dawb me me. Cov mis molecular ZN (C17H35COO) 2, cov qauv molecular RCOOZnOOCR (R yog pawg alkyl sib xyaw hauv cov kua qaub stearic), yooj yim hlawv, lub zog tshwj xeeb 1.095, qhov taw qhia nws tus kheej 900 ℃, qhov ceev 1.095, qhov taw qhia yaj 130 ℃, roj. Nws tsis yaj hauv dej, ethanol thiab ether, tab sis yaj hauv ethanol kub, turpentine, benzene thiab lwm yam organic solvents thiab acids. Zinc stearate raug cua sov thiab yaj hauv cov organic solvent, thiab tom qab ntawd txias kom tsim cov tshuaj colloidal, uas raug rhuav tshem mus rau hauv stearic acid thiab zinc ntsev sib xws thaum ntsib cov kua qaub muaj zog. Nws yog lubricating, hygroscopic, tsis muaj tshuaj lom, me ntsis khaus, tsis muaj kuab paug, thiab tsis muaj kev phom sij. Zinc stearate thiab calcium stearate tuaj yeem sib cais los ntawm cov khoom uas zinc stearate yaj hauv benzene thiab calcium stearate tsis yaj hauv benzene.
